1 Corinthians 15:56

"Now the sting of death is sin; and the power of sin is the law." Seest thou how the discourse is of the death of the body? therefore also of the resurrection of the body. For if these bodies do not rise again, how is death "swallowed up?" And not this only, but how is "the law the power of sin?" For that "sin" indeed is "the sting of death," and more bitter than it, and by it hath its power, is evident; but how is "the law also the power" thereof? Because without the law sin was weak, being practised indeed, but not able so entirely to condemn: since although the evil took place, it was not so clearly pointed out. So that it was no small change which the law brought in, first causing us to know sin better, and then enhancing the punishment. And if meaning to check sin it did but develop it more fearfully, this is no charge against the physician, but against the abuse of the remedy. Since even the presence of Christ made the Jews' burden heavier, yet must we not therefore blame it, but while we the more admire it, we must hate them the more, for having been injured by things which ought to have profited them? Yea, to show that it was not the law of itself which gives strength to sin, Christ Himself fulfilled it all and was without sin. But I would have thee consider how from this topic also he confirms the resurrection. For if this were the cause of death, viz. our committing sin, and if Christ came and took away sin, and delivered us from it through baptism, and together with sin put an end also to the law in the transgression of which sin consists, why doubtest thou any more of the resurrection? For whence, after all this, is death to prevail? Through the law? Nay, it is done away. Through sin? Nay, it is clean destroyed.

Nothing could be truer. For a prohibition always increases an illicit desire so long as the love of and joy in holiness is too weak to conquer the inclination to sin. So without the aid of divine grace it is impossible for man to love and delight in sanctity.
